Hey, I managed to get some sound out from my computer for the first time just now. It seems I was missing something really silly. Happens all the time

.
It's like this: I had gone into 'input rename' and set the 'CD' digital coax input (that I was using) to 'computer'. But I had not set the 'input select' to pick 'computer' for that input. It was pointing to 'V-Aux' and I really don't know why I did that. So, though I was setting 'audio select' to 'optical/digital', I was hearing nothing. Now that's really simple.
I guess I was confused by all the labeling. I really don't understand why there is any need to label any of the inputs. They should just say these are the HDMI inputs and these are the digital coax inputs and so on. Then you connect whatever you want to them without needing to make sure the name on the input selector matches the label of that input.
Now I will have to go and figure out how to get the best quality sound out of this. Thanks.
